The first step to making your deck look new again is with a careful cleaning. You can buy a chemical cleaner at your home improvement center. Apply the cleaner with a garden sprayer, followed by a pressure wash of railings and benches. Be extremely careful with the pressure washer, because if you place the nozzle too close to the wood the water can damage it. Use a power deck scrubber to clean the deck boards.
After a thorough cleaning, you’ll want to sand your deck, remove splinters, and inset any popped nails. Finally, apply stain or sealer with a sprayer followed by back brushing into the grain of the wood. Contributing editor Danny Lipford walks you through these steps in our video.
